Zyvox also received approval for treatment of hospital-acquired pneumonia and complicated skin and skin structure infections, including cases due to methicillin-resistant Staphylococcus aureus (MRSA). In addition, approval was granted for treatment of community-acquired pneumonia and uncomplicated skin and skin structure infections. Infections due to Enterococcus faecium and MRSA are a particular problem in hospitalized or immuno-compromised individuals. These organisms are often resistant to multiple antibiotics. Vancomycin has, for many years, served as the treatment of last resort for these infections. But its effectiveness has fallen in recent years as drug-resistant strains have appeared. http://www.webmolecules.com/cgi-bin/webmolpage.cgi?vancomcn.m3d Zyvox is the first in a new class of synthetic drugs (oxazolidinones). Pharmacia and Upjohn, based in Kalamazoo, Mich., developed Zyvox and will market it in the United States. ------------------ WebMolecules News Sponsor ------------------ Join the Elementalists at SCIENCEbase.com for the latest reactive science communication on the Web from award winning science writer David Bradley. http://www.sciencebase.com/ ------------------( Please Visit This Sponsor!)------------------ S U G G E S T I O N B O X ----------------------------------------------------------------- Is there a new feature you would like to see at WebMolecules?

by chen zhongping 16 May '00

16 May '00

Dear list memebers, I've got a few questions about starch, I really hope these questions are not too off the list. I really appreciate your time and your kind reply. Thank you very much in advance. 1. Where can I find reference about potato starch or modified potato starch on the internet? 2.Can anyone give me some clues about the application of modified potato starch in industry. 3. Where can I find reference about modified starch's application in the paper-making and print ink industry on the internet? Can modified starch substitute CMC in paper-making industy especially in the coating process. Best wishes. Have a nice day!

Software for Review
by Dr. Stephen R. Heller 15 May '00

15 May '00

15 May 2000 Subject: Computer Software for Review As the Software Review Editor for the ACS Journal of Chemical Information and Computer Science (JCICS) I often get software for review in the journal. I have three (3) new software products. I am looking for people who are willing to review these software products. In return for the review which is published in JCICS you get to keep the software or database. The review should be completed in 1-3 months. The length of the review is 4-10 double spaced typed pages. Sample reviews can be found in most of the recent issues of JCICS. Please try to give me some (short) reason to choose you over another person. I have tried this approach for about the past seven years and it is working reasonably well. (REMINDER: For those who haven't finished your reviews of software sent months and months ago, this last sentence does not apply to you!) As a result, I am continuing this new method to find reviewers using this e-mail/user group system. I reserve the right to abandon this if it is a problem, or inappropriate. I will not notify people if I have found a reviewer. If you don't hear from me within a few days I have chosen someone else to review the particular package. As I get many, many, (too many) replies to this message, please do not respond after 19 May, 2000 (Friday), as I am sure the software will be gone by then. I can be reached on Internet (STEVE(a)HELLERS.COM) PLEASE BE SURE TO INCLUDE AN STREET ADDRESS, PHONE, and FAX NUMBER!!! (I often send the software by Federal Express.) Without this information I WILL NOT consider your request. Steve Heller The packages I now have are: 1. Un-Scan-It, version 5.0: Automated Digitizing Software from Silk Scientific.

question about modified starch
by chen zhongping 23 Apr '00

23 Apr '00

Hello every, Recently, we developed a unique modified starch technology and we want to apply it to industry. But we need investment and we are not very clear about the market situation. Can anybody give me some advice about where to find investors who will be interested in develop chinese market or apply this technology to some foreign countries. And if anyone is interested in it, can join us. My tel number can be found at the auto-signature. If you are interested in it, I can give you more details about it. Thank you very much for your kind reply. The following is the introduction of our technology. If the following message annoy you, I will be terribly sorry for that. A starch-originated substitute for the peach gum On the outer package of some food grade material or product, adhesive agent is needed to disperse different pigments and coat on to paper. The essential characteristics for the agent include dispersivity, adhesiveness, levelling, rewetting and film forming capability. Originally, Arabic gum was chosen as the main adhesive agent. It can satisfy most purposes. However, Arabic gum is relatively expensive. Later it was substituted partly by refined peach gum. The dark brown sticky liquid peach gum gel has been proved effective in most circumstances. Its price is much cheaper than Arabic gum. Recently because the demand for peach gum has increased, and the quality of this gum depends on productive regions, on the processing technology and on the weather, end users of these natural gums suggested the possibility to substitute them to some degree with starch derivatives. For starch is plentiful and relatively cheap. Great efforts have been paid on research to find out suitable substitutes derived from different kinds of starch. In China several companies and research institutes showed interest in pursuing this goal. After more than half a year perseverance, a modified maltodextrin has been prepared which can meet the demand. In many tests, this kind of maltodextrin showed superiority over peach gum. For example, it is pale yellow, rather than dark brown; when used to disperse pigments like Red 5FRK and phthalocyanine blue, this maltodextrin gives out more satisfactory coating layers on paper. To prepare such modified maltodextrin, first the starch is liquefied to soluble maltodextrin, then undergoes chemical reactions at the presence of certain catalysts. Before concentration, the reacted material is clarified and purified. The samples demonstrated good levelling and adhesive power, its dispersivity, hydrophilicity and film forming characteristics are better than peach gum, it also has rewetting ability. It is estimated that the cost for producing this maltodextrin will be economic if on a reasonable scale. It will be a competitor to the peach gum. Have a nice day!

Netscape 6 and Chemistry
by Rzepa, Henry 07 Apr '00

07 Apr '00

I have occasionally posted regarding the characteristics of various Web browsers. Since recently the first release of Netscape 6 was posted (previously known as Mozilla) I thought I would report on some aspects of its behaviour. We have created a little test page at http://www.ch.ic.ac.uk/chemime/tests/ which attempts to test various ways of invoking chemical content, both legacy and the forward looking XML variety. Netscape 4 has some problems with HTML 4 standards, particularly tests 11-13. As it happens, Internet Explorer 5.0/5.5 does not do at all better on these tests, implying that proper support for the HTML 4 standard is patchy. There is ONE browser that did pass the tests, icab for Macintosh! Now I find that Netscape 6 for Mac (not tried Windows yet) sort of passes these tests. Test 11 is fine; Test 12 only fails because the Chime plugin is not happy with Netscape 6 (this may be different on Windows). Netscape 6 is not yet totally happy with XML (we have another set of tests for this which I will release shortly) but seems to be getting there! When its finished, it looks like it will go a long way to catching up with IE5, and in areas such as mobile phones etc, may even overtake it! By the way, does anyone have any chemical pages written in WML (Wireless markup language, essentially a very simple HTML).
